I find that Oberlander desserts are as good as the year-round desserts. I also think that Pesach raspberry jelly rings are as good as the year round ones. I also had these Absolutely gluten free potato starch crackers (OU-P) that were really good this year.
I do think trying to eat natural for Pesach is also a great idea.
I actually did make a sweet potato kugel/pie/breakfast/dessert this year that was so good that I made it 2 shabbatot since (sweet potatoes, maple syrup, a little grated ginger, cinnamon, allspice, raisins, vanilla extract, eggs, toasted pecans, a little brown sugar, and baked. My mother likes marshamallows on top, as this reminds her of Thanksgiving).
On the topic of Israel, I was actually reasonably pleased with the quality of nosh from Israel this Pesach (bamba, bissli, etc.) But natural eating is a good idea for many reasons, not only on Pesach, but all year round, as well.
